Abstract :
In the previous work, non-imaging focusing heliostat that consists of m n facet mirrors can carry out continuous astigmatic correction
during sun-tracking with the use of only (m + n 2) controllers. For this paper, a simplified astigmatic correction of non-imaging
focusing heliostat is proposed for reducing the number of controllers from (m + n 2) to only two. Furthermore, a detailed optical analysis
of the new proposal has been carried out and the simulated result has shown that the two-controller system can perform comparably
well in astigmatic correction with a much simpler and more cost effective design.
